The centrepiece of the village Mauterndorf is medieval Burg Mauterndorf . Dominating a rocky outcrop, this 13th-century castle was built by the archbishops of Salzburg on the site of a Roman fort. The castle now houses a regional museum and provides the backdrop for various cultural events. It is believed that in the Middle Ages the main road passed directly through the castle courtyard and tolls were extracted from road users.
